I very much need to try the ArgyllCMS software w/ my ColorMunki.
Do you find the 500 patch profiles better than the CM software ones?
How much better are they? By a large degree, or slightly so?
I bought my ColorMunki expecting good, but not necessarily great, profiles. That's what I've found. I also bought it hoping that I could leverage ArgyllCMS to take things up a notch.
I've profiled a canvas, a coated canvas, a matte paper and a gloss paper with ArgyllCMS. The ArgyllCMS profiles have been better. My comparison was to ColorMunki profiles, other than the canvas profile which was provided by the manufacturer.
My first profile was done using ~1300 patches and the rest use more than 2000 patches. I can't speak to 500 patch profiles, although that may change shortly. I have a paper where I don't want to commit to 12 letter sized sheets, and I plan to profile it with either 392 or 784 patches.
ArgyllCMS does a nice job of matching to the paper white point, and I find that skins tones come out very nice. I find them noticeably better than the CM profiles. I also see a better print to screen match with the ArgyllCMS profiles, which means I have confidence in these profiles whereas I'm now reluctant to use the CM profiles. When I compare gamut volumes my ArgyllCMS profiles come out somewhat larger.
